In a preceding paper1) I stated that preformed or inorganic sulphate is poor in human milk positive to Arakawa's reaction and that it is abundant in Arakawa-negative milk. Human milk poor in inorganic sulphate is therefore probably a “good milk” generally Now as Arakawa-negative milk is a milk secreted from a B-avitaminotic body, then it will be natural to conclude that, if vitamin B, is admini-stered to a mother with milk abundant in sulphate, then she will come to secrete sulphate-poor milk.
In the present paper I administered vitamin B1 to 10 lactating women and saw the change of sulphate content in their milk. And the result is that sulphate content decreased in most cases on administra-tion of the vitamin B1. And the decrease of it will occur more early than the improvement of Arakawa's reaction.
